randomHexColorCode

Generates a random hexadecimal color code.

Use Math.random to generate a random number and limit that number to fall in between 0 and 16 using Math.floor. Use the generated random number as index to access a character from 0 to F. Append it to color till the length is not 7.

const randomHexColorCode = () => '#'+(Math.random()*0xFFFFFF<<0).toString(16);
// randomHexColorCode() -> "#e34155"
// randomHexColorCode() -> "#fd73a6"
// randomHexColorCode() -> "#4144c6"
